Spiderman couple Andrew Garfield and Emma Stone are world's favourite hearththrons just now but apparently they have "kissing issues".Or that was the idea we got in this week's Saturday Night Live, hosted by Garfield. Stone showed up many times to show her support and during one of her appearances, Peter Parker and Gwen were supposed to kiss. Only they failed to do it convincingly despite the director giving them helpful suggestions such as "make it romantic", "keep it natural" and "like in real life". When nothing worked, Coldplay frontman and Gwyneth Paltrow's ex-husband Chris Martin made his move.The singer donned a blonde wig as he held Garfield in his arms and said, "Now you listen to me, you beautiful spidery man, with great power comes great responsibility and our responsibility right now is to make sweet, sweet love. So why don't you go ahead and show me that beautiful tongue."As the actor resisted, Martin said, "Come on, come to papa!"
